Unit and network activity of neurons in the visual, sensorimotor, and frontal cortical areas and dorsal striatum was investigated in cats under conditions of choice of the reinforcement value depending on its delay. The animals did not differ from each other in behavior. After immediate or delayed responses cats got low- or highly-valuable reinforcement, respectively. Single-unit activity in the visual and sensorimotor cortical areas and dorsal striatum was similar during performance of immediate and delayed responses. However, significant inhibition was observed in the frontal neurons during the delay period. The network activity of visual and frontal cortex displayed smaller number of interneuronal interactions during delayed responses as compared to immediate reactions. The network activity of neurons in the brain structures under study pointed to the interstructural interaction, but only during delayed reactions, steady interneuronal communication was observed between the frontal cortex and dorsal striatum. Thus, both types of estimation of cellular activity revealed differences in the ensemble organization during different types of behavior and showed specific reactions of neuronal ensembles.
在根据强化物延迟情况选择强化物价值的条件下，对猫的视觉、感觉运动和额叶皮质区域以及背侧纹状体中的神经元的单位活动和网络活动进行了研究。这些动物在行为上彼此没有差异。即时或延迟反应后，猫分别获得低价值或高价值的强化物。在即时和延迟反应过程中，视觉和感觉运动皮质区域以及背侧纹状体中的单位活动相似。然而，在延迟期观察到额叶神经元有明显抑制。与即时反应相比，延迟反应期间视觉和额叶皮质的网络活动显示出较少的神经元间相互作用。所研究的脑结构中神经元的网络活动表明存在结构间相互作用，但仅在延迟反应期间，在额叶皮质和背侧纹状体之间观察到稳定的神经元间通信。因此，两种类型的细胞活动估计都揭示了不同类型行为期间整体组织的差异，并显示了神经元群体的特定反应。
